There are several websites in Panama like Groupon in the U.S. that offer deals on restaurants, spas, events, and tours for over half off. Subscribing to these can be a great way to save money whether you live here or are just visiting. Here is a list of the websites that offer discounts in Panama:
Oferta Simple: This is the most popular discount site in Panama and I think they usually have the best deals.
Quiero Ofertas: They usually have a mix of products, restaurants, and spa treatments on discount.
Yo Dileo: Mostly spa treatments and sometimes concert ticket discounts.
Gustazos: Newest discount site in Panama filled with great deals!
Be sure to read the fine print before you buy an offer from these websites. Many of them can have date and time restrictions.
